The last number in the electron configuration.
For example, 2-8-5, the valence electron is 5

The elections in the outer shell of an atom are called "valence electrons." These electrons are crucial in determining how an atom interacts with others, as they are involved in forming chemical bonds. The number of valence electrons influences an element's reactivity and its position in the periodic table.
The elections in the outermost shell of an atom are called valence electrons. These electrons play a crucial role in chemical bonding and reactions, as they are involved in forming bonds with other atoms. The number of valence electrons determines an element's chemical properties and its ability to form compounds.
The electrons that form bonds are called valence electrons. These electrons are in the outer most shell of an atom.
Elections in the outermost energy shell of an atom are called valence electrons. These electrons play a crucial role in chemical bonding and reactions, as they are involved in interactions with other atoms. The number of valence electrons determines an element's reactivity and its ability to form bonds with other elements.
To find the valence of an element on the periodic table, look at the group number. Elements in group 1 have 1 valence electron, group 2 have 2 valence electrons, and so on. For transition metals, the valence can vary so it's determined by the charges in their compounds.
the number of valence electrons is the number group on the table its on
Lanthanum has 3 valence electrons
Krypton has 8 valence electrons.
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)

These electrons are crucial in determining how an atom interacts with others, as they are involved in forming chemical bonds. The number of valence electrons influences an element's reactivity and its position in the periodic table.
To find the number of valence electrons of an element using the periodic table, you can look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.

To find the number of non-valence electrons in an atom, you first need to determine the total number of electrons in the atom by looking at its atomic number on the periodic table. Next, subtract the number of valence electrons, which are the electrons in the outermost energy level of the atom, from the total number of electrons. The remaining electrons, which are not in the outermost energy level, are the non-valence electrons.
To find the valence electrons in an atom, look at the group number on the periodic table. The group number tells you how many valence electrons an atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
